MAGE-A4-specific TCR gene-transduced T lymphocytes TBI-1201

Autologous human T lymphocytes transduced with a retroviral vector encoding a T-cell receptor (TCR) specific for the human melanoma antigen A4 (MAGE-A4), with potential immunostimulatory and antineoplastic activities. Upon isolation, transduction, expansion ex vivo, and reintroduction into the patient, MAGE-A4-specific TCR gene-transduced T lymphocytes TBI-1201 binds to tumor cells expressing MAGE-A4. This may result in both an inhibition of growth and increased cell death for MAGE-A4-expressing tumor cells. The tumor-associated antigen MAGE-A4 is overexpressed by a variety of cancer cell types.
